This interactive exercise focuses on how line graphs can be used to represent mathematical data and provides an opportunity to translate actions from a story into graph form, then to write your own story to coincide with a line graph.

Detailed math tutorial features notes and examples that discuss graphing lines and introduces the concept of slope, the standard form of the line, the point-slope form, slope-intercept form, and parallel and perpendicular lines.

This comprehensive study guide highlights the main terms and formulas needed to review lines in the coordinate plane. Examples are included.

Given points that two lines go through or the graph of each line, classify the lines as parallel, perpendicular, or neither.

Use this guide to practice graphing linear functions using Claris Works with your students. The lesson walks you through the process of setting up Claris Works step-by-step.

Watch how a graph is altered when key elements of the equation change. This lesson focuses on how to manipulate the equation of a line in slope intercept form to match the graphs provided deepening the understanding of both the slope and...

Learn about the vertical line test for functions by trying to connect points in the plane to build a function. When you have connected all of the points, you will be told if your graph is a valid graph of a function.

In this interactive, use logic to solve three riddles involving high-jump performers in a flea circus. Then, using knowledge of inequalities, place the fleas in the appropriate range on a vertical number line. Numbers are randomized so...

In this lesson, students are to interpret graphs with equations of lines.

This study guide on lines in a coordinate plane covers key terms, what different line slopes look like, postulates about parallel and perpendicular lines, the slope-intercept equation, how to graph parallel and perpendicular lines, and...

Solve a number riddle by finding the point of intersection for two lines. This video focuses on finding the solution for a system of equations, they are represented as an algebraic expression and a set of linear equations that are...

This math tutorial shows the relationship of a slope to a straight line and how to write equations in point-slope or slope-intercept form.

The purpose of this task is to introduce students to systems of equations. It takes skills and concepts that students know up to this point, such as writing the equation of a given line, and uses it to introduce the idea that the...

In this task, 8th graders are shown the graphs of two lines with the same slope. They are given the equation for the first line and the coordinates of a point on the second and are asked to find the equation for the second line. Aligns...

This section explores the process for finding inverses of functions, and then proving the function and its inverse algebraically. Additionally, it explores how the graphs of functions and their inverses compare to each other, and it...

Learners will understand key concepts of data analysis and their graphic representations. Students will construct and interpret data tables, line plots, box-and-whisker plots and stem-and-leaf plots, scatterplots with line of best fit,...

Take a look at inverse functions from their definition to graphing them. This site also shows you how to find the inverse of a function.

This micro-field guide was created by 5th and 6th graders in Marlboro, Vermont. Groups of 3 or 4 students worked together to investigate their own 3 by 3 foot research plot, over multiple visits, and then created a field guide to their...

See if the King, Queen, or one of their loyal subjects can figure out how to solve the problem of their crummy bridge. This animated video from Math Snacks focuses on using what you know about converting measurements and reading a line...

A collection of lesson ideas, a practice activity, and teacher resources for exploring regression analysis.

Given an experimental situation, the student will write linear functions that provide a reasonable fit to data to estimate the solutions and make predictions.

[Free Registration/Login may be required to access all resource tools.] Here you will explore displays of data using bar charts, histograms, pie charts and boxplots, and learn about the differences and similarities between them and how...

Students will explore the data on boat registrations and manatee deaths in Florida. They will use the data, the graph of the data and the line of best fit to make predictions about the relationship of the data.

View the graph and the equation of the line tangent to any function at any point on the function.
